*Update from my last problem. It was a blown fuse*

So i have my kenwood aftermarket radio all wired up and went to put in into the car. I got power to the thing but i was getting no sound to the speakers. I also wasn't getting door chimes which come from the speakers. So im assuming that the radio wasn't sending a signal to the stock amp. I have the wire connected(blue white) that should have the radio and amp talk to each other through the GMO4 Interface.

I put the stock one back in and it works fine. So i know the amp is working.

 

Bump.

 

guess no one has an ideas

 

Maybe Milhouse might have an idea when he sees this. He's really good with car audio.
